CROSS REFERENCE TO THE RELATED APPLICATIONS

This application is the national stage entry of International Application No. PCT/CN2020/133936, filed on Dec. 4, 2020, which is based upon and claims priority to Chinese Patent Application No. 202011211167.4 filed on Nov. 3, 2020, the entire contents of which are incorporated herein by reference.

TECHNICAL FIELD

The present disclosure relates to the technical field of production of low-temperature heating non-combustion products, and in particular to a multi-purpose internal component for an aerosol-generating product, and an aerosol-generating product having the multi-purpose internal component.

BACKGROUND

Low-temperature heating non-combustion products can greatly reduce harmful substances in smoke and avoid passive smoking, so that the low-temperature heating non-combustion products are highly praised by many tobacco enterprises.

An existing low-temperature heating non-combustion product mainly includes an aerosol-generating component, a multi-functional component, and a filter component. The aerosol-generating component mainly contains a granular, shredded, powdery, flaky, or pasty smoke-generating material. The aerosol-generating component is heated to produce an aerosol for a user to inhale. When the aerosol-generating component contains a granular, powdery, or pasty smoke-generating material, a distal lip end of the aerosol-generating component needs to be sealed separately, and a proximal lip end of the aerosol-generating component also needs to be provided with a blocking member, thereby preventing the granular, powdery, or pasty smoke-generating material from scattering.

The multi-functional component is adjacent to the aerosol-generating component and is configured to achieve the following functions: 1. The multi-functional component includes an air-flow channel to allow an aerosol generated by the aerosol-generating component to reach the filter component. 2. The multi-functional component can contain a material with cooling, fragrance-enhancing, and harm-reducing functions, which reduces the temperature of the aerosol, enhances the fragrance of the aerosol, and reduces harmful ingredients in the aerosol. 3. When the aerosol-generating component contains a granular, powdery, or pasty smoke-generating material, the multifunctional component can prevent the granular, powdery, or pasty smoke-generating material from scattering.

The filter component is close to the proximal lip end of the aerosol-generating product and commonly uses cellulose acetate tow as the filter material. However, the filter component has the following problems: 1. There is a single selection for a form of the filter material, that is, only the specific tow form can be adopted, and a pasty, fragmented, powdery, or granular filter material cannot be used. 2. It is not easy to add functional materials to the filter component. Due to the limited form of the filter material, when it is desired to add a cooling, fragrance-enhancing, or harm-reducing material, only cooling and fragrance-enhancing capsules can be added.

The present disclosure is proposed to solve the above-mentioned problems.
